In diborane, the two H−B−HH-B-H angles are nearly :

A

60∘,120∘60^{\circ} , 120^{\circ}

B

95∘,120∘95^{\circ} , 120^{\circ}

C

95∘,150∘95^{\circ}, 150^{\circ}

D

120∘,180∘120^{\circ} , 180^{\circ}

Answer

95∘,120∘95^{\circ} , 120^{\circ}

Explanation

Solution

Structure of diborane is as follows : undefined Thus the H−B−HH - B - H angles are nearly 97∘,120∘97^{\circ}, 120^{\circ}.
